Genes affected

CCS (HGNC:1613): (copper chaperone for superoxide dismutase) Copper chaperone for superoxide dismutase specifically delivers Cu to copper/zinc superoxide dismutase and may activate copper/zinc superoxide dismutase through direct insertion of the Cu cofactor. [provided by RefSeq, Jul 2008]

The c.683G>C (p.G228A) alteration is located in exon 8 (coding exon 8) of the CCS gene. This alteration results from a G to C substitution at nucleotide position 683, causing the glycine (G) at amino acid position 228 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
